Specification of Letters Patent.

Patented oca 1e, 190e.

Application med May 9, 190e. serial No. 315.996.

,To all whom it may concern.-

'Beit known that I, CHARLES O. HILER, a citizen of the United States, residing at Oelwein, in the county of Fayette and State of Iowa, have invented certain new and useful Improvements in Gravity-Conveyers; and I do declare the followin to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,y reference being had to the accompanying drawings, and to the figures of vreference marker thereon, which form a part of this specification. j

This invention relates to gravity-conveyers; and the object is to provide an efficient, cheap, durable, and portable device for conveying from one place to another bricks, rocks, and manyother heavy articles bythe action of their own weight or gravity. This and other objects I attain by the novel construction and arrangement of parts illusof which three are shown in Fig. 3.

trated in the accompanying drawings, in which- Figure 1 is a top orplan view of a portion of my brick and stone carrier or conveyer, showing both straight and curved parts of it. Fig. 2 is a side elevation of Fig. 1 with rollers omitted. Fig. 3 is an enlarged side elevation of a piece of the conveyer. Fig. 4 is an enlarged side view of one" of the roller-barings,

i0. 5 is a sectional-'view onrthe line a a of Fig. 4? with a conveying-roller in diametrical section added.l Fig. 6 is a diametrical section-of a portion-of a conveying-roller cast in one`piece.

Fig. 7 is a view similar to Fig. 6, but with the4 roller formed of several parts. Fig. 8 is a diametrical section of one of the tapering rollers used where the conveyer-track curves laterally. Fig. 9 is a side elevation of a piece of T-shaped rail used for track andv a ballbearing of modified construction secured thereon.v Fig. 10 is a sectional view on the line b b in Fig. 9 with a roller added.

Referring tothe drawings by reference-nuv inerals, 1 designates the ground, platform, or

,son

usually a floor, upon which are placed supports 2 of such gradually-reduced height that the rails 3 resting thereon form an inclined track, which whenprovided with rollers'will -allow bricks and other heavy objects to revolve the ro1lers, ,andthus move from one end to the other of the track.

. The track eo'n'sists of two parallel rails 3 secured `together by transverse braces 4,

is divided into sections'which are detachably 'bolted together, as shown at 5 in Fig. 3, where the overlapping ends of the rails are penetrated by easily-removable bolts.

Upon each rail is secured by bolts, screws, or rivets 6 a series of ball-bearings 7, in which revolve the journals 8 of rollers 9 and 9b, parallel rollers 9 being usedwhere the track runs straight and taperingrollers, like 9b, being used where the track curves laterally.

The roller-bearings may be of the form 7, which consists of two plates bolted together at 12, whereby an annular groove 13 for the balls 14 of the ball-bearing is formed. In this case the rail is formed with notches 15 to receive the ball-bearings, and the latter are formed with perforated ears 16, which are secured by bolts, screws, or rivets 6 to the margins 18 between the notches of the rails; but the bearing ma also be formed, as in Fio's. 9 and 10, where t e rail has no notches, and the ball-bearing 7"L is formed with downwardlyextending arms orfcheeks 16, which are bolted to the rail, two cheeks bein shown, while a single one may also answer t e purpose for conveyers doing only light work.

The rails may be of plain dat iron bars turned edge .up or they may be made of angie-iron having a bottom flange like 19 in ig. 10 or of T-iron having fianges like 19.and 19a in said View. j The body of the rollers I prefer to make of wrought-iron tubing and secure in the ends thereof malleable, cast, or steel journals 8, which are formed with a plu 20 fitting tightly in the end of the tube, an is provided near its shoulder 22, with an annular recess 21, into which the ver;T end of the tube 9 is closed, as in Fig. 7, by suitable dies, so tightly that the plug can never work loose, much less get out of the tube. v

In Fig. 6 is shown how the tube 9a and the journalS may be cast integral. This may be done with both-ends of the tube or only with one end,.asin Fig. 8, where the tapering tube 9b may have one journal cast with itand a plug secured in the other end. In either case the plug and journal may be solid or may preferably be cored out, as shown at 23.

In the use of the device the necessary sections of track, straight or curved, or both straight and curved, are put together and mounted on supports of sultable variation in height. The bricks, rocks, pig-iron, or other articles are then placed upon the rollers and allowed to move along to the lower end of the ICO track. Where the conveyed articles are too small to move properly upon the rollers, boxes are place-:l upon the rollers with the articles or goods 'in theln; but having shown such boxes in another application, filed on April 23, 1906, Serial No. 313,150, it is unnecessary to here show then; again.

Having thus described my invention, what l claim, and desire tosecure by Letters Patont, is-

1. A gravlty-conveyer comprising a pair of rails secured together in parallel position, ball-bearings secured at intervals upon the rails and rollers extending transversely between the rails and having journals resting in the ball-bearings; said rollers being made of wrought-iron tubes and the journals being cast and formed each with anenlar ed part ittng the end ofthe tube tightly an( having a shoulder fitting against the end of the tube.

'in presence of tWo 2v. A gravity-conveyer comprising a pair of rails secured together in parallel position, ball-bearings secured at intervals upon the rails, rollers extending transversely between v the rails and having l]ournals resting in the ball-bearings; said rollers being made of Wrought-iron tubes and the journals being cast and formed each with an enlar ed part fitting the end of the tube tightly and having a shoulder fitting against the end of .the tube it also having an annular groove near the shoulder and the edges of the end of the tube pressed into said groove.

In testimony whereof I affix my signature Witnesses.
